3. The computer-implemented method of claim 2 , further comprising: receiving, by the computer, a scanned electronic copy of the encrypted token visualization element from a client device; and transmitting for display, by the computer to the client device, information associated with the document on a graphical user interface of the client device.

4. The computer-implemented method of claim 3 , wherein the information associated with the document comprises the document, an identity of the first user, the one or more edits, the electronic signature of the first user, a timestamp associated with the one or more edits, and a timestamp associated with the electronic signature of the first user.

5. The computer-implemented method of claim 2 , further comprising: uploading, by the computer, the one or more edits to a blockchain.

6. The computer-implemented method of claim 1 , wherein the first user and the second user are a same person.

7. The computer-implemented method of claim 1 , wherein the handwritten signature is captured through a user interface displayed on a smartphone application.

8. The computer-implemented method of claim 1 , further comprising: receiving, by the computer, one or more edits to the document and an electronic signature from a third user; in response to validating the received electronic signature of the third user based on stored physical features of a handwritten signature of the third user: updating, by the computer, the document based upon the one or more edits of the third user; and linking, by the computer, the electronic signature of the third user with the document.

9. The computer-implemented method of claim 1 , wherein the encrypted token visualization element is a quick response (QR) code or a bar code.

10. A system comprising: a non-transitory storage medium storing a plurality of computer program instructions; and a processor electrically coupled to the non-transitory storage medium and configured to execute the computer program instructions to: extract and store physical features of a handwritten signature of a first user; receive a request to generate a document from a second user; set a document permission for the first user based on an input from the second user; receive an electronic signature corresponding to a second handwritten signature of the first user, the electronic signature received in accordance with the document permission set by the computer; in response to the processor validating the electronic signature of the first user based on the stored physical features of the handwritten signature of the first user: link the document with the electronic signature of the first user based upon the document permission; and affix an encrypted token visualization element on the document, the encrypted token visualization element configured to indicate a link between the electronic signature of the first user and the document.

11. The system of claim 10 , wherein the document permission includes an edit permission, and wherein the processor is configured to further execute the computer program instructions to: receive data records indicating one or more edits to the document from a device associated with the first user; and in response to the processor validating the electronic signature of the first user based on the stored physical features of the handwritten signature of the first user: update the document based upon the one or more edits, wherein the encrypted token visualization element is configured to retrieve the one or more edits.

12. The system of claim 11 , wherein the processor is configured to further execute the computer program instructions to: receive a scanned electronic copy of the encrypted token visualization element from a client device; and transmit for display to the client device, information associated with the document on a graphical user interface of the client device.

13. The system of claim 12 , wherein the information associated with the document comprises the document, an identity of the first user, the one or more edits, the electronic signature of the first user, a timestamp associated with the one or more edits, and a timestamp associated with the electronic signature of the first user.

14. The system of claim 11 , wherein the processor is configured to further execute the computer program instructions to: upload the one or more edits to a blockchain.

15. The system of claim 10 , wherein the first user and the second user are a same person.

16. The system of claim 10 , wherein the handwritten signature is captured through a user interface displayed on a smartphone application.

17. The system of claim 10 , wherein the processor is configured to further execute the computer program instructions to: receive one or more edits to the document and an electronic signature from a third user; in response to the processor validating the received electronic signature of the third user based on stored physical features of a handwritten signature of the third user: update the document based upon the one or more edits of the third user; and link the electronic signature of the third user with the document.

18. The system of claim 10 , wherein the encrypted token visualization element is a quick response (QR) code or a bar code.

19. A computer-implemented method comprising: responsive to a computer setting one or more document permissions for a document associated with one or more users based on an input received from at least one user, validating, by the computer, an electronic signature corresponding to a handwritten signature of a user based upon stored physical features of the handwritten signature; affixing, by the computer, an encrypted token visualization element on the document, the encrypted token visualization element configured to indicating a link between the electronic signature of the user and the document associated with the one or more users; receiving, by a computer from a client device, a scanned electronic copy of the encrypted token visualization element; retrieving, by the computer, a plurality of data records of a sequence of events and corresponding timestamps associated with the document; and transmitting, by the computer to the client device, the sequence of events and corresponding timestamps configured to be displayed as a chain of custody and audit trail of the document in a graphical user interface of the client device.

20. The computer-implemented method of claim 19 , wherein the sequence of events include at least one of a creation of the document, an edit to the document, a signature added to the document, an access to the document, a transmission of the document from a first user to a second user, a completion of the document.
